Abstract (en)

[origin: WO0017125A1] This is a method for producing manufactured aggreates from coal combustion by-products having sulfur. Recycle fines containing calcium hydroxide, and aluminum-containing material, and water are mixed together to form a feed mix which is agglomerated into a an gglomerated product. The agglomerated product is combined with curing fines which contain calcium oxide which together form a blended mix. The blended mix is cured using the moisture in the blended mix which is used to exothermally hydrate the calcium oxide in the blended mix to form calcium hydroxide and which autogenically provides the required heat for curing and converts the calcium oxide in the blended mix to a dry calcium hydroxide-containing material to form aggregate products and dry fines. The aggregate products are separated from the dry fines, the dry fines are recycled to the mixing step and the aggregates are taken and used as a useful product for other purposes.
